ELECTRIC CLIPPJER.

Application'led September 22, 1922. Serial No. 589,919. i

To all whom 'it may conceom:

lBe Vit known that I, LEO J. WAHL, a citizen of the United States, residing at Sterling, in the colinty of Whiteside and State of Illinois, have invented certain new and useful Improvements inElectric Uli pers, of which the. following is a specificatlon.

My invention lhas reference to electric clippers such as are specially designed for use in barber shops, and belongs to'that type of instrument wherein the actuating devices are contained within the handle, or casing of the tool. ln 7devices of this class which are now in use if the blades become worn or get out of adjustment,-it is a ditlicult matter to regulate the same, and the removal and replacement of the blades calls for the use of a considerable' amount of time.

.the device.

@ne of the purposes of the present invention is to `provide a novel control mechanism for the'movable clipper blade, whereby a very delicate adjustment of such blade can be made with relationi to the stationary blade of the tool.

Another purpose of the invention is to support the/cmovable clipper blade in such a manner that-the same can be quicklyT removed from the fqtool, and sharpened, or replaced by another blade, if desired..

Another object of. the invention is to provide means for exertinga desired amount of pressure upon the movable blade, lat a point near the operating edge thereof.

Another purpose of the invention is to increase the general eiciency and'durability of the tool. f

The above-mentioned, and other features and advantages of the invention will be more fully understood from ,the following specification, reference'l being had to the accompanying drawings, in which: f

Fig, 1 is a 'vertical longitudinal section of Fig. 2 is a plan view thereof, with the upper casing plate'l removed. A Fig. 3 is a detail of the plate 16.. Fig. 4 is a detailofthe blade 4, in perspective.

side elevation of the tool, corn- 'lfhe invention comprises a hollow -handle `or casing, torined of parts 1 and la, the part i 1a being attached to the other part so .that

it can be disconnected therefrom, if desired. When united, the two parts form an of the `bears against the inner Yment of the plate 16 instrument which can be conveniently grasped by the hand of the operator. To one end of the part 1 is secured a stationary clipper blade 2, provided with the usual series of teeth 3, and slidable on the blade 2 is a blade 4, provided at its outer edge with a series of teeth 5, coacting with the teeth 3 when the tool is in operation. 'ln an. enlargement 6 of the casing is secured an electro-magnetic coil 7, at one end of which is supported a plate VV8, by means of a resilient arm 9, attached at one of its ends -to the inner face of the casing 1, by means of a bolt 10. The plate 8. which is of softer metal than the arm 9, is in close proximity to the core 11 of the coil 7 and operates as an armature therefor, so that upon such coil being suitably energized, a rapid vibratory movement is given to said plate. The plate 8 is bent at its free end into an arm 12, to the outer face of which is secured Va frame 13. having a pair of' parallel plates provided with threaded perforations to receive a sim`- ilarly threaded screw 14, the end of which engages a small depression 15 in the blade 4; Between the frame 13 and arm 12 is secured a thin plate 16, the lower edge of which acts as a support for a rib 17 on the blade 4, and prevents such blade from twisting cr turning upon the pivot formed by the end screw 14, while the blade is in operation. The lower edge of the plate 16 also edge of the blade,

in place by means of a pair of screws 19, passing throughopenings 20 in the plate 16. rllhese openings are of greater diameter than the screws, permitting of an adjustvertically or transversely.

rlhe spacing of the plate 8 with relation to the coil can be regulated by means of an adjustment screw 21 in thewall of the casing 1, and the coil 7 is tted with wires 22, passing through openings in the small end 'of the handle, and designed for connection with a suitable source of electrical power.

-ln practice, these wires would be formed intoa cord, and dtted with a socket for cennection with the usual mercantile system of light -or power. lf the current of electricity which is supplied is of an alternating or intermittent\ character, a rapid vibratory movement will be given to the arm 8,-thereby imparting to the blade 4 a rapid csail# frequently desired.

lating action transversely of the tool. This operates the clipper teeth in the usual manner', with the desired results.

By a proper operation of the screw l-jt, by means of a thumb-turn 18 thereon, the pressure exerted by said screw upon the blade 4 can be gradually increased or diminished, at will. The screw is positioned so that the force thereof will be impartedv nearest. the cutting edge of the blade, as shown, as a result of which the response of the blade to the action of the screw is quicker, and the application of the force thereof more positive, than if such screw were stationed at a point farther from said cutting edge. The screw is preferably mounted in the frame 13 so that there will be sufficient friction upon the threads of the screw to prevent accidental turning thereof, and in case the threads should become worn, resulting in a loosening of the. screw, this can be overcome by bringing the supporting plates of. the frame: a little closer together. To accomplish this the the screw is lremoved from the frame. the frame detached from the tool` and the plates pounded or otherwise forced a little closer together. They then have the operation of a lock-nut upon the screw.

It will be evident that avery limited amount `of rotation ofthe screw 14 will serve to release the blade 4, which can be slipped from its position as soon as the screw and blade are disengaged. This is a great advantage where the clipper is subjected to considerable use, and a change of blades is Changes can be made in the form and arrangement of the device, without depart.-

ing from the spirit of the invention, as herein set forth and claimed.

What I claim and desire to secure by Letters Patent, is:
